    In graceful shutdown `setTimeout` is used. Which one is better? Anayway it's better to
be consistent in scheduler usage. Plus we do why need two schedulers? Can one work for both
tasks? Plus if one drillbit is unavailable, there is no need to check memory.

>             Project: Apache Drill
>          Issue Type: Bug
>          Components: Web Server
>    Affects Versions: 1.12.0
>            Reporter: Kunal Khatua
>            Priority: Major

> When viewing http://<hostname>:8047/metrics#gauges
> The gauges reset to near zero values and does not seem to update.
> Tracing the server calls made, I see the following:
> {code:json}
> {version: "3.0.0", gauges: {G1-Old-Generation.count: {value: 0}, G1-Old-Generation.time:
{value: 0},…},…}
> counters :
>   {drill.connections.rpc.control.encrypted: {count: 0},…}
> gauges :
>   {G1-Old-Generation.count: {value: 0}, G1-Old-Generation.time: {value: 0},…}
> histograms :   {,…}
> meters : {}
> timers : {}
> version : "3.0.0"
> {code}
> This looks incorrect and would explain why the metrics appear to be incomplete.
